Anyone have any science ebook recommendations that meet the following criteria?

1) not overly technical (I don't have a science degree)
2) available without DRM (and preferably in a format that suits the PRS-700 without conversion).
2a) Must be available to buy from Australia
3) I've just read 'A Brief History of Time' and want some more books with a similar tone.
4) Not a text book

Any science topic is welcome, especially evolution, space exploration, anything to do with the brain/mind.

I couldn't find anything on Fictionwise. I like the sound of the Bill Bryson book but can't find it without DRM.

There are more popular science ebooks available now than in the past, but they are almost all DRM-laden. One I recommend is The Selfish Gene: 30th Anniversary Edition by Richard Dawkins. It is available as a Secure Adobe PDF from ebooks.com. They actually have a nice selection of recent mainstream popular science ebooks, but all with DRM.

Bill Bryson's A Short History of Nearly Everything. Love everything he does but this one is particularly good.

Mary Roach - Particularly "Stiffs". The only nonfiction book about cadavers that will make you laugh out loud? Is that inappropriate? ...sigh....

Also, if you are all environmentally minded "The World Without Us" by Arthur Weisman (I think). Not as good as Bryson's (Bryson is quite humorous) but an interesting concept. National Geographic did a great documentary similar to this which was quite good.

ETA Just noticed you already know about the Bill Bryson. Sorry can't help you out with drm free.

If you're not averse to listening to science lectures, I recommend audiobook courses from The Teaching Company ( http://www.teach12.com ) - on very wide range of subjects, and almost always very interesting to listen to. As far as I know, they're not released as ebooks, but since I found them, I prefer to listen to such course to reading a science ebook.
Another company offering similar range of insteresting courses is Modern Scholar.

If you enjoyed A Brief History of Time, you might enjoy The Elegant Universe by Brian Greene (I've no idea if it's available as an ebook, and it's Sunday arvo, so if you want to go looking, be my guest ). It becomes "technical" of sorts, as it progresses, but its beauty is that it leads logically and gently into it, such that it doesn't feel like you're drowning in conceptual mindwarps (which is a nifty trick, considering the subject matter ). I actually found it a more enjoyable and a bit easier (though much longer) read than A Brief History of Time (and that's without denigrating the latter at all).

Yep, they're both excellent books.

I also enjoyed Marcus Chown's 'The Magic Furnace' about the origin of atoms. (I keep meaning to look for more by him.)

Richard Fortey's 'Life: an unauthorised biography' is a fascinating account of life on Earth.
